Use a callback .

In your directive, set a scope property that will receive controller callback :

app.directive('exemploDiretiva', function () {
    return {
        restrict: 'AE',
        template: '<h3>Olá!</h3>',
        scope: {
            chamadaCallback: '&' // <- Define uma referência de função externa
        },
        link: function (scope, element, attrs) {
        }
    };
});

This is done by setting the value in view :

<exemplo-diretiva chamada-callback="meuMetodoDoController(arg1)"></exemplo-diretiva>

Note that while the definition is in the camelCase ( chamadaCallback ) format, the parameterization must be done in lowercase-dash ( chamada-callback ) format.

With this done, create the meuMetodoDoController method in controller - it will be invoked when, in policy, you invoke the callback as follows:

scope.chamadaCallback('qualquerParametroQueVoceQuiser');
